Key Insights and Takeaways

  • AI is keeping users on Google.
  • SEO is about visibility, not just clicks.
  • Attribution is harder, rethink how you track success.
  • Diversification is key.
  • Adapt or be left behind.

Let’s dive in.

SEO Is Not Dead, and No, the Sky Is NOT Falling

The latest recurring theme in digital marketing is “zero-click” search. This trend is not new, but it has gained renewed attention with the aggressive rollout of AI Overviews, GPT-Search, and other AI-driven experiences.

While these developments may seem like a perfect black-swan event, the reality is far less dramatic.

Rand Fishkin, former CEO of SEOMoz (now Moz) and current CEO of SparkToro, has been researching zero-click search for years. However, the message has only recently gained traction. Fishkin has highlighted that as Google continues expanding its features in search results, more users find answers without leaving the search page or interacting with other Google properties instead of external sites.

This represents the continued closing of Google’s walled garden.

Understanding Zero-Click Search Trends

Traditionally, digital marketers used simple equations to predict search traffic. These equations helped estimate traffic and conversions for a given web page based on its search engine results page (SERP) ranking. Search volume was distributed across ranking positions on a SERP, with traffic and conversions estimated accordingly.

However, as Google introduces AI-driven search features, like AI-generated answers, knowledge panels, and featured snippets directly on the SERP, the traditional click-through rate (CTR) model is evolving. Fewer users click through to websites, making it harder for businesses to capture organic traffic.

For marketers, this shift requires new strategies that focus on optimizing content for these features to ensure visibility even when traditional click-through models fail.

Fishkin’s research provides the following critical insight:

Only 41.5% of clicks result in traffic to an external site (organic or paid), meaning most user engagement stays within Google’s ecosystem—images, videos, maps, etc.

But, if we go back to an earlier study, we can get more perspective from this: less than half of Google searches resulted in a click in 2019, and this was pre-pandemic. So, search experts have been modeling this behavior for some time now—don’t panic. Just because you appeared or a resource you made is served in the search results, and you didn’t get a click doesn’t mean the sky is falling.

It’s a different opportunity for brand presence if you can get served up in those other features alongside the standard ten blue links, most of which rely on technical SEO, not necessarily the “creative” involved.

Nothing here changes the part of advertising that is about repetition and meeting the “first moment of truth” -—the part that involves your brand being top of mind when someone takes an action. What it changes is what can be measurably attributed. The attribution is more difficult to produce the analytics “walk” to conversion.

Zero-Click Search in Healthcare Marketing

For healthcare marketers, zero-click search presents unique challenges:

Desktop searches are common for research-oriented users, while mobile searches drive more action-based behaviors. If most of your converting traffic comes from mobile, zero-click search could reduce click-through rates by pushing standard results further down the page.

Complicating matters, AI Overviews do not always cite top-ranking organic results. Instead, they pull from various sources trained on different datasets than traditional organic search.

Here is an example of the number of potential SERP features (e.g., non-traditional 10-blue-link results) across all verticals, according to SEMrush Sensor:

  • All Verticals (Mobile, U.S.): 9.37%
  • Health Vertical (Mobile, U.S.): 12.75%

Here is what that looks like for mobile in the health vertical at 12.75%:

Each industry is affected differently. For example, e-commerce faces new shopping experiences, while AI-driven restaurant recommendations reshape local search rankings.

The Concern Over Zero-Click

The real issue isn’t zero-click search itself but rather the convergence of new SERP features—most notably AI Overviews, which began rolling out aggressively after the 2024 Google I/O developer conference. These features have yet to be fully monetized under traditional paid search models, creating uncertainty for SEO and PPC professionals. Some providers, such as Perplexity, have even floated the potential of bidding on the next possible question asked of its AI experiences.

Expect volatility as search behaviors continue evolving. Diversifying traffic sources is essential as information-foraging habits change with new platforms and technologies.

The Impact on SEO and Paid Search

Recent studies from Seer Interactive indicate that AI Overviews are affecting CTRs for both organic and paid results. This is compounded by seasonal fluctuations in cost-per-click (CPC) during Q4.

A decade ago, Google introduced Hummingbird and RankBrain (algorithm updates) to address the 15% of daily searches that were previously unseen. This marked the shift toward query intent rather than keyword-matching.

Today, searches are evolving again—moving away from long-tail queries (3-5 words) to more complex search prompts (8-10 words or more).

With the rise of “Circle to Search,” Discover, GPT-Search, Gemini, and Perplexity, search habits are changing rapidly. A new norm is emerging where prompts replace traditional queries. Though still a small percentage, this trend has grown significantly in under six months.

Here’s a screenshot of a site we monitor that’s been seeing some of these shifts in rankings and click-through rates where AI Overviews are becoming more prevalent by the day.

CTR tends to be higher for queries with more words, highlighting a shift in SEO strategy away from optimizing for short, generic terms. Instead, SEO now focuses on broader topics and topic spaces, aligning with user behaviors rather than prioritizing specific marketing channels. The key insight isn’t just that CTR is lower in some cases, but rather what user behavior reveals—emphasizing that traffic from AI-generated overviews and search experiences may be of higher quality and more engaged.

Navigating SEO in the Era of Zero-Click Search

Let’s cut through the noise—zero-click search isn’t new, and no, SEO isn’t dead. But Google’s aggressive push for AI Overviews, search automation, and its ever-growing walled garden means the game is changing.

The way users interact with search results has been shifting for years, and now, with AI-driven answers appearing more prominently, traditional organic traffic is taking a hit.

But here’s the real takeaway: It’s not about clicks disappearing. It’s about visibility shifting. If you’re still optimizing like it’s 2015, you will struggle.

If you embrace these changes, your brand can thrive—even without a click.

What’s Really Happening with Zero-Click Search?

For years, digital marketers relied on simple formulas:

  • Ranking position = predictable click-through rates (CTR)
  • More rankings = more traffic
  • Traffic = conversions

That model doesn’t hold up anymore. Google is keeping more users on its own properties, serving up AI-generated summaries, featured snippets, People Also Ask (PAA) results, and local packs—all without requiring users to visit a website.

Rand Fishkin’s research at SparkToro found that only 41.5% of searches lead to external clicks—meaning most user engagement happens within Google’s own ecosystem. And if you look at AI-generated results, things get even murkier.

But before you panic, take a step back. Less than half of searches resulted in a click before AI Overviews even rolled out, and SEOs have been navigating this landscape for years.

This isn’t a crisis—it’s an evolution.

Adapting Your SEO Strategy to Zero-Click Search

If clicks are harder to come by, the focus should shift to brand presence and authority within search results. Here’s how:

1. Own More SERP Real Estate

Instead of obsessing over blue links, focus on the other search features where your brand can appear:

  • Featured Snippets
    Format content concisely (40-60 words) with bullet points or numbered lists.
  • People Also Ask (PAA)
    Structure content to answer related questions users are searching for.
  • Google Business Profile & Local Pack
    Essential for local businesses looking to maintain visibility.
  • Video & Image Search
    Optimize visual content for Google’s expanding search experiences.

2. Leverage Google’s Own Platforms

Google is prioritizing its own ecosystem—so make sure you’re showing up where users are:

  • Google Discover
    Mobile-friendly, engaging content can drive traffic from personalized feeds.
  • YouTube SEO
    Video results dominate AI-driven search experiences.
  • Google News & Web Stories
    Ideal for news publishers and thought leadership content.

3. Shift from Keyword-First to Topic-First SEO

Google’s AI models don’t just match keywords—they understand topics. That means SEO should focus on comprehensive content clusters rather than just targeting isolated keywords.

Example:

  • Old Strategy: Targeting “best email marketing tools”
  • New Strategy: Building a full content ecosystem around email marketing (e.g., “how to personalize email marketing with AI,” “best email sequences for SaaS growth,” “email automation best practices”).

Google wants depth and expertise, not just a page with the right keywords.

4. Optimize for AI-Driven Search Experiences

With the rise of AI Overviews, Google’s search experience is shifting from traditional keyword queries to longer, natural-language prompts. Optimize content to reflect this shift:

  • Use conversational, question-based headings (e.g., “How does AI improve content creation?” instead of “AI content tools”).
  • Structure pages with scannable answers—clear, concise responses to complex queries.
  • Make use of FAQ schema to surface your content in AI-generated answers.

5. Diversify Your Traffic Sources

If Google is keeping more users on its own platform, you can’t rely on organic search alone. Build multiple channels:

  • Email Marketing
    Grow a subscriber base that isn’t dependent on search algorithms.
  • LinkedIn & Twitter Thought Leadership
    Drive authority and direct engagement.
  • Paid Search & Social Ads
    Fill traffic gaps with targeted campaigns.
  • Referral Partnerships & PR
    Increase brand awareness outside of Google’s reach.

SEO is still a major traffic driver, but the brands that survive will be the ones that don’t put all their eggs in Google’s basket.

What This Means for the Future of SEO

Search is not dying—but it is evolving.

  • AI Overviews will continue reshaping search behavior.
  • Click-through rates will decline on informational queries but remain strong on high-intent searches (e.g., transactional or local search).
  • Attribution will become harder, but that doesn’t mean brand impact is lower—it just means tracking needs to adapt.

The key takeaway? SEO success is no longer just about driving clicks—it’s about owning visibility.

If your brand appears in AI-generated answers, featured snippets, and search experiences, you’re winning—whether or not the user clicks through.

The SEO landscape is shifting, but this isn’t the first time—and it won’t be the last. The smartest marketers won’t resist these changes. They’ll adapt. Instead of chasing outdated tactics, focus on visibility, credibility, and engagement across multiple platforms.

Zero-click search doesn’t mean zero opportunity. The question isn’t “How do I get more clicks?” ask, “How do I ensure my brand stays top-of-mind—whether users click or not?”

That’s where the real SEO battle is being fought. And the brands that figure it out? They’ll be the ones winning in the new search era.
